It is made of HDPE material added with anti-ultraviolet agent, and the filter layer uses 200g/㎡ short-fiber needle-punched geotextile, effectively blocking impurities and sediment in landfills. Its water permeability reaches 120L/(m·h), meeting the demand for large-flow leachate collection. It has a compression strength of 400kPa, which can withstand the rolling of heavy vehicles in landfill operations, and its leachate corrosion resistance meets national standards. It has a service life of over 50 years with no regular maintenance required.
It has an outer diameter of 150mm, inner diameter of 110mm, perforated diameter of 12mm with spacing of 40mm, standard length of 100m per roll, material thickness of 3mm, filter layer weight of 200g/㎡, water permeability of ≥120L/(m·h), compression strength of 400kPa, leachate pH resistance range of 3-12, operating temperature range of -10℃ to 80℃, complies with GB 16889 standard, aging resistance of ≥50 years of outdoor use, and weighs approximately 3.5kg per meter.
It is suitable for leachate collection systems of urban domestic waste landfills, drainage systems of industrial hazardous waste landfills, leachate collection of composting plants, and drainage of ash yard of waste incineration plants. It can be laid at the bottom and slope of landfills to effectively collect leachate and prevent water accumulation.
